Variety denomination: ‘MEICOSME’.

CROSS REFERENCE TO RELATED APPLCIATIONS

This application claims priority to Plant Breeders’ Right ApplicationNumber 2021/2142, which was filed at Community Plant Variety Office inthe European Union on Aug. 27, 2021, the contents of which are herebyincorporated by reference for all purposes.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was Feb. 22, 2021 in France.The first offer for sale of the new variety was by the inventor oranother who obtained the new variety directly or indirectly from theinventor. No plants of the new variety have been sold in this country oranywhere in the world, nor has any disclosure of the new plant beenmade, more than one year prior the effective filing date of thisapplication, and such sale or disclosure within one year was eitherderived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new variety of bedding rose plant of the present invention wascreated by controlled breeding at Le Cannet des Maures, Var, France byartificial pollination wherein two parents were crossed which previouslyhad been studied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was an unnamed seedling (not patented) from the cross betweenthe ‘MEINOIRAL’ variety (not patented) and an unnamed seedling (notpatented). The male parent (i.e., the pollen parent) of the new varietywas the ‘MEIZMEA’ variety (U.S. Plant Pat. No. 20,175).

The parentage of the new variety can be summarized as follows:

(‘MEINOIRAL’ x Unnamed Seedling) x ‘MEIZMEA’

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

The new variety has been found to undergo asexual propagation in LeCannet des Maures, Var, France by a number of routes, including eyebudding, softwood cuttings, and hardwood cuttings. Asexual propagationby the above-mentioned techniques in Le Cannet des Maures, Var, Francehas shown that the characteristics of the new variety are stable and arestrictly transmissible by asexual propagation from one generation toanother. Accordingly, the new variety undergoes asexual propagation in atrue-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of rose plant of the present inventionpossesses the following combination of characteristics:

-   (a) forms dark pink purple colored flowers,-   (b) produces single flowers, and-   (c) exhibits a bushy growth habit.

The new variety well meets the needs of the horticultural industry. Itcan be grown to advantage as ornamentation in parks, gardens, publicareas, and in residential settings. Accordingly, the plant isparticularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguishedfrom its ancestors. More specifically, the unnamed seed parent(‘MEINOIRAL’ x Unnamed Seedling) produces medium pink colored flowers,whereas the new variety produces dark pink purple colored flowers. Inaddition, the ‘MEIZMEA’ variety (i.e., pollen parent) displays flowerswith a light pink colored spot at the base of the flower, whereas thenew variety displays a yellow-white colored spot at the base of theflower. Moreover, the new variety can be readily distinguished fromother similar non-parental varieties. For example, the ‘RADRAZZ’ variety(U.S. Plant Pat. No. 11,836) produces red colored semi-double flowers,whereas the new variety produces dark pink purple colored singleflowers.

The new variety has been named ‘MEICOSME’.
